  <h1 class="topictitle1">Known Limitations</h1>

  
  <div><p>Below are some known limitations categoried by module within the current release of the DITA Open Toolkit.</p>

    <div class="section"><h2 class="sectiontitle">Transformation to PDF and Word RTF</h2>
      
      <ol>
        <li>You can change the styles of the output file by using tools in Microsoft<sup>®</sup> Word rather than specifying the styles before transforming.</li>

        <li>If there is a cross reference referring to an URL in the DITA source file, the link should be completed defined with the proper internet protocol. For example, specify <kbd class="userinput">http://www.ibm.com</kbd> instead of <kbd class="userinput">www.ibm.com</kbd>.</li>

        <li>Flagging, revision bar and filtering are not supported in PDF and Word RTF output.</li>

        <li>Morerows attribute of the table element used to generating vertically merged cell is not supported in PDF output.</li>

        <li>Style attributes for table are not supported in Word RTF output.</li>

        <li>Complex cases dealing with table in list are not supported in Word RTF.</li>

        <li>There might be no output style applied on contents of some tags in Word RTF output compared with other output.</li>

      </ol>

    </div>

    <div class="section"><h2 class="sectiontitle">HTML to DITA migration</h2>
      
      <ol>
        <li>Since Xalan doesn't allow to set the public and system IDs dynamically using a variable, when Xalan is used as the default XSLT processor, the output will contain: <pre class="codeblock">&lt;!DOCTYPE topic PUBLIC "{$publicid}" "{$systemid}"&gt;</pre>
<p>Suggest to use Saxon as the processor to fix this problem. For other information on this problem, see the section "Other general migration notes" in the first developerWorks article.</p>
</li>

        <li>Currently, the stylesheet can't handle HTML files within namespace like below: <pre class="codeblock">&lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;</pre>
<div class="note"><span class="notetitle">Note:</span> This limitation has been fixed in release 1.2.1, please refer to the <a href="DITA-h2d.html">Migrating HTML to DITA</a> for detail information.</div>
</li>
